Abstract

An assembly for recycling a solvent from a contaminated solvent solution includes a reservoir module connected to a recycler module. The reservoir module includes a mounted reservoir including an interior volume and a removable lid that reduces the interior volume and includes an access port. The recycler module includes a distillation assembly and an air handler assembly. The distillation assembly includes a distiller and a conduit including a condenser and a sight glass. The air handler assembly includes a duct having an intake port, an exhaust port and a source of air flow. The condenser is disposed within the duct and the sight glass is disposed external to the duct.

Claims (18)

1. An assembly for recycling a solvent from a contaminated solvent solution comprising: a reservoir module connected to a recycler module; the reservoir module including a mounted reservoir disposed therein; the reservoir including a side wall, a bottom wall and a top wall that define an interior volume and a removable lid; the lid including a first portion that extends below the top wall into and reduces the interior volume and an access port disposed in the first portion; the recycler module including a distillation assembly and an air handler assembly; the distillation assembly including a distiller and a conduit connected to the distiller and adapted for connection to a source of the contaminated solvent solution; the conduit including a condenser and a sight glass; the air handler assembly including a duct having an intake port, an exhaust port and a source of air flow connected to the duct; wherein the condenser is disposed within the duct and the sight glass is disposed external to the duct; wherein the conduit includes, in series, a first portion adjacent the distiller that is disposed within the duct, a second portion that is disposed external to the duct and a third portion that defines the condenser.

2. The assembly as recited in claim 1 , wherein the bottom wall includes a back edge disposed above a front edge.

3. The assembly as recited in claim 1 , further comprising a substantially vertically aligned conduit that connects the reservoir and the distiller.

4. The assembly as recited in claim 1 , further comprising a lock-out including a valve having a handle connected to a conduit that connects the reservoir and the distiller that prevents removal of the lid when the handle is disposed in an open position and permits removal of the lid when the handle is disposed in a closed position.

5. The assembly as recited in claim 1 , further comprising a slot formed in a bottom wall of the recycler module that defines an inlet pathway between an exterior of the recycler module and an interior of the recycler module and an opening in the duct adjacent the distiller that defines an outlet pathway between the interior of the recycler and the exterior of the recycler module thereby defining an ambient cooling passageway.

6. The assembly as recited in claim 1 , wherein the recycler module further comprises a cover including an inlet opening disposed aligned in registration with the intake port and an outlet opening disposed aligned in registration with the exhaust port.

7. The assembly as recited in claim 1 , wherein the recycler module further comprises a cover including a crowned top.

8. The assembly as recited in claim 1 , wherein the distiller further comprises a modular, non-welded construction.

9. The assembly as recited in claim 1 , wherein the distiller further comprises a top plate, a bottom plate, a tube disposed between the top plate and the bottom plate, that collectively define a distillation chamber, and a fastener that extends between the top plate and the bottom plate and retains the tube therebetween.

10. The assembly as recited in claim 1 , wherein the distiller further comprises a baffle disposed adjacent a port connected to the conduit.

11. The assembly as recited in claim 1 , wherein the distiller has a longitudinal axis disposed non-vertical.

12. The assembly as recited in claim 11 , wherein the distiller further comprises a top plate and a bottom plate disposed normal to the longitudinal axis.

13. The assembly as recited in claim 1 , wherein the distiller further comprises a heating element that, when activated by a controller, maintains the contaminated solvent solution disposed in the distiller above a boiling temperature for the solvent and below an offset from an auto-ignition temperature for the solvent.

14. The assembly as recited in claim 13 , wherein the heating element is removably connected to a top plate for independent replacement.

15. The assembly as recited in claim 1 , further comprising a pressure relief valve in direct communication with a distillation chamber defined within the distiller.

16. The assembly as recited in claim 1 , wherein the duct includes a panel disposed adjacent to the condenser and removably connected to the duct to facilitate access to the condenser.

17. The assembly as recited in claim 1 , wherein the solvent is selected from the group consisting of a hydrocarbon-based solvent, a petroleum-based solvent, N-Methyl-2-pyrrolidone and butanone.

18. An assembly for recycling a solvent from a contaminated solvent solution comprising: a reservoir module connected to a recycler module; the reservoir module including a mounted reservoir disposed therein; the reservoir including a side wall, a bottom wall and a top wall that define an interior volume and a removable lid; the lid including a first portion that extends below the top wall into and reduces the interior volume and an access port disposed in the first portion; the recycler module including a distillation assembly and an air handler assembly; the distillation assembly including a distiller and a conduit connected to the distiller and adapted for connection to a source of the contaminated solvent solution; the conduit including a condenser and a sight glass; the air handler assembly including a duct having an intake port, an exhaust port and a source of air flow connected to the duct; wherein the condenser is disposed within the duct and the sight glass is disposed external to the duct wherein the source of airflow is a fan disposed within the duct and wherein the fan includes an axis of rotation disposed substantially vertical and the condenser includes a conical configuration aligned substantially symmetrical about the axis of rotation.
